摘要：

This paper describes microphone array that can be used for sound localization and sound capture. The system has omni-directional sensitivity, and can be as a tele-microphone for apropriate direction. Sound capture by microphone array is achieved by Sum and Delay Beam Former (SDBF). Simulation of sound pressure distribution of 32 & 64ch circular microphone array are shown. According to simulation results, dedicated Firewire (IEEE1394) 32-channel board are developed with maximum sampling rate of 11kHz sample. The 32ch circular microphone array system is evaluated by using frequency components of the sound.
